There are 10 ways to choose two variables from X1, X2, S1, S2, S3 and assign the value 0.
To choose two variables from X1, X2, S1, S2, and S3, and assign the value 0, you can use the combination formula. In this case, there are 5 variables (n=5) and you want to choose 2 (r=2). The combination formula is C(n, r) = n! / (r!(n-r)!).
Applying the formula:
C(5, 2) = 5! / (2!(5-2)!)
C(5, 2) = 120 / (2! * 3!)
C(5, 2) = 120 / (2 * 6)
C(5, 2) = 120 / 12
C(5, 2) = 10
So, there are 10 ways to choose two variables from X1, X2, S1, S2, and S3, and assign the value 0.

2. List net profit if you invested $500.00 in each of the listed stocks (below) 5 years ago, you must show the math so I can see if it is correct:
Chipotle: 1,708.29 USD
+36.12 (2.16%) today
Nike: 122.64 USD
+2.54 (2.11%) today
Amazon: 103.29 USD
+1.29 (1.26%) today
Snap Inc.: 11.21 USD
+0.30 (2.75%) today
Answer:
To calculate the net profit for each of the listed stocks, you can use the formula:
Net Profit = (Current Price - Purchase Price) * Number of Shares
Assuming you invested $500 in each stock 5 years ago, the purchase prices would be as follows:
Chipotle: $649.85 (based on the current price of $1,708.29)
Nike: $71.45 (based on the current price of $122.64)
Amazon: $45.60 (based on the current price of $103.29)
Snap Inc.: $15.49 (based on the current price of $11.21)
To calculate the number of shares you would have purchased at the time, you would divide $500 by the purchase price. For example, for Chipotle:
Number of Shares = $500 / $649.85 = 0.769 shares
Using this formula, the net profit for each stock would be:
Chipotle: (1,708.29 - 649.85) * 0.769 = $764.28
Nike: (122.64 - 71.45) * 7.006 = $359.62
Amazon: (103.29 - 45.60) * 10.920 = $630.58
Snap Inc.: (11.21 - 15.49) * 32.281 = -$137.31 (assuming you bought fractional shares)
Therefore, your total net profit would be $1,616.17.
Note that this calculation does not take into account any transaction fees or taxes that may be incurred in buying and selling the stocks.
I made a long explanation because you wanted me to explain step by step.
For Nike:
1.5 years ago the stock was at 63.59 USD, so buying $500 of Nike stock would give me 7.85 stocks (Purchase amount/stock price) or (500/63.59:7.85).
Stock is now valued at $122.64 USD, so I own $963.78 in stock (Stock price x Stock owned) or (7.85 X 122.64 = $963.78).
Net profit is $463.78 (Total of current owned stock - initial investment) or ($963.78 - $500 = $463.78).
For Amazon:
1.5 years ago the stock was at $1,765.13 USD, so buying $500 of Amazon stock would give me 0.283 stocks (Purchase amount/stock price) or (500/1,765.13:0.283).
Stock is now valued at $3,369.19 USD, so I own $953.63 in stock (Stock price x Stock owned) or (0.283 X 3,369.19 = $953.63).
Net profit is $453.63 (Total of current owned stock - initial investment) or ($953.63 - $500 = $453.63).
For Snap Inc.:
1.5 years ago the stock was at $17.46 USD, so buying $500 of Snap Inc. stock would give me 28.63 stocks (Purchase amount/stock price) or (500/17.46:28.63).
Stock is now valued at $11.21 USD, so I own $321.36 in stock (Stock price x Stock owned) or (28.63 X 11.21 = $321.36).
Net loss is $178.64 (Total of current owned stock - initial investment) or ($321.36 - $500 = -$178.64).
Based on the net profit, Chipotle and Amazon have performed well over the past 5 years, with net profits of $1,230.51 and $453.63 respectively. Nike has also performed well with a net profit of $463.78. However, Snap Inc. has decreased in price over the past 5 years and resulted in a net loss of $178.64.
convert the Roman Numeral CCCXL (with two lines above it) to Hindu-Arabic form
Each line above the numbers multiply it by 1000. So this number is being multiplied by 1000000.
Each "C" is equal to 100, since there are "CCC" the number is 300.
"XL" is equal to 40, because "X" is equal to 10 and "L" is equal to 50, but since he X is on the left of the L we subtract them.
The number CCCXL is then 340, but there are the two lines. So we have:

When comparing functions, such as Seth’s scenarios for travelling to school, will the function with the greatest initial value continue to be the greatest as time increases?
No. The pace of change affects the y-value, therefore having a higher beginning value does not guarantee it. The output may decrease if the function with the bigger beginning value has a slower rate of change.
This is further explained below.
What are functions?Generally, No. Even if the function had a higher beginning value, it does not always follow that it would always have a higher y-value. This is because the y-value also relies on the rate of change.
In conclusion, If the function with the higher beginning value has a slower rate of change, it is possible that the output may become smaller at some time in the future as a consequence of this.

The profit margins (return on sales) for each division are approximately :Division A = 10.85%,Division B = 9.11% and The calculations for the year would be:Net Income = $85,428,Return on Assets = 18.9%.
To compute the profit margins (return on sales) for each division, we divide the profit by the sales and multiply by 100 to express the result as a percentage.
For Division A:
Profit Margin = (Profit / Sales) * 100
Profit Margin = ($230,000 / $2,120,000) * 100
Profit Margin ≈ 10.85%
For Division B:
Profit Margin = (Profit / Sales) * 100
Profit Margin = ($34,700 / $381,000) * 100
Profit Margin ≈ 9.11%
To calculate the net income and return on assets for Polly Esther Dress Shops Inc., we use the given information.
Net Income = Profit Margin * Sales
Net Income = 7% * $1,220,400

Step-by-step explanation:
Firstly we would start off by simplifying the equation by doing the order of operations backward (PEMDAS -> SADMEP) and multiply -4 and -3 which would equal a positive 12
Next, we would divide 12 and -6 and get a negative 2
Finally, we would have the equation 1 - 12 + (-2)
We would solve the equation to get -13/(-1)³
This would make the -13 into a positive since any number over one is a whole number. -13 is getting divided by (-1) 3 times so it converts to a positive, then a negative, then back to a positive.

the mean value of land and buildings per acre from a sample of farms is $1500, with a standard deviation of $100. the data set has a bell shaped distribution. assume the number of farms if the sample is 70. use the empirical rule to estimate the number of farms whose land and building values per acre are between $1400 and $1600
The sample mean is X[bar]=$1500
The sample standard deviation is S=$100
The sample size is n=70
The data set has a bell shaped distribution
The empirical rule states that
The values $1400 and $1600 are within one standard deviation away from the mean:
X[bar]+S=$1500+$100=$1600
X[bar]-S=$1500-$100=$1400
Following the rule you can expect 68% of the sample to be between them.
Whats left to do is to calculate the 68% of the sample

use cylindrical coordinates. evaluate e (x − y) dv, where e is the solid that lies between the cylinders x2 y2 = 1 and x2 y2 = 49, above the xy-plane, and below the plane z = y 7.
After considering the given data we conclude that the value derived after performing integration by applying cylindrical coordinates is -1029π / 3
The solid E is the region between the cylinders x² + y² = 1 and x² + y² = 49, above the xy-plane, and below the plane z = y/7. We can apply cylindrical coordinates to evaluate this integral.
The limits of integration for r are 1 and 7. The limits of integration for theta are 0 and 2π. The limits of integration for z are 0 and r/7.

A car vehicle price history for a certain make and model contains the following list of yearly price values: $21,000 $18,900 $17,010 $15,309 $13,778.10 $ 12,400.29 The original price of the car was $21,000. It exponentially depreciated to $18,900 after 1 year and continued depreciating by the same percentage each year thereafter . What will the value of the car be after 8 years ? $
The value of the car after 8 years is $9,039.81
What is the Percentage?
Percentage, which is a relative figure used to denote hundredths of any amount. Since one per cent is equal to one-tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.
As an illustration, 1% of 1,000 chickens is equivalent to 1/100 of 1,000, or 10 birds, and 20% of the quantity is equal to 20% of 1,000, or 200. These relationships may be generalized as x = PT/100 where x is the amount equal to a certain percentage P of T and T is the total reference quantity selected to represent 100%. As a result, T is 1,000, P is 1, and x is determined to be 10 in the case of 1 percent of 1,000 chickens.
As we can see each year 10% of the actual value of a car the decrease
For example, $21,000 decreased to $18,900
21000-18000/21000 = 0.1x 100% = 10%
Next year
$18,900 decreased to $17,010
18900-17010/18900 = 0.1x100% = 10%
in 6th year the price will be

14. the mean price of a pound of ground beef in 75 cities in the midwest is $2.11 and the standard deviation is $0.56. suppose the histogram of the data shows that the distribution is unimodal and symmetrical. a local grocer is selling a pound of ground beef for $3.50. what is this price in standard units? assuming the empirical rule applies, would this price be unusual or not? round to the nearest hundredth.
For a unimodal distribution which is symmetrical with a mean price of $2.11 and standard deviation of $0.56, a local grocer’s price of $3.50 in standard units would be 2.282 and it is unusually expensive.
A unimodal distribution refers to a distribution with one clear peak as the values increase to a single highest point after which they. It can be symmetrical or non-symmetrical. A symmetrical distribution refers to a distribution whose mean, mode, and median are all equal.
The standard score (z) is given by:
z = (x - µ)/σ where µ is the mean and σ is the standard deviation.
To determine the value of z for $3.50 price:
z = (3.5 – 2.11)/0.56 = 2.482
From the z-table, the probability of z ≥ 2.282
P (z ≥ 2.282) = 1 – P (z < 2.282) = 1 – 0.98876 = 0.0112 or 1.12%

Sabiendo que la tangente son 4/3 dime el cos y sen estando el angulo en el tercer cuadrante de la circunferencia
Answer:
sen α = - 4/5
cos α = - 3/5
Step-by-step explanation:
tang α = 4/3
De la relación fundamental de la trigonometría sabemos:
sen² α + cos²α = 1
Dividiendo la ecuación anterior por cos² α
sen²α/cos²α + cos²α / cos²α = 1 / cos² α
tang²α + 1 = 1/ cos² α
(4/3)² + 1 = 1/ cos² α ⇒ 16/9 + 1 = 1/ cos² α
1/ cos² α = ( 16 + 9 ) / 9
1/ cos² α = 25/9
cos² α = 9/25
cos α = 3/5
y para calcular el sen α
sen² α = 1 - cos²α
sen² α = 1 - 9/25
sen² α = ( 25 - 9 )/ 25
sen² α = 16/25
sen α = 4 / 5
Ahora bien el angulo α está en el tercer cuadrante, en ese cuadrante tanto el seno como el coseno son negativos.
Respuesta:
sen α = - 4/5
cos α = - 3/5
